Departments of Pathology Oncology Ophthalmology Otolaryngology-Head and Neck Surgery, The Johns Hopkins University School of Medicine, Baltimore, MD Institute of Pathology, Friedrich-Alexander-University Erlangen-Nürnberg, University Hospital, Erlangen, Germany Department of Laboratory Medicine and Pathobiology, University of Toronto Department of Pathology & Laboratory Medicine, Mount Sinai Hospital Department of Pathology, Sunnybrook Health Sciences Centre Department of Pathology, University Health Network, Toronto, ON Department of Pathology and Laboratory Medicine, University of Kentucky College of Medicine, Lexington, KY Department of Pathology, University of Texas Southwestern Medical Center, Dallas, TX Department of Pathology, Kaiser Permanente Walnut Creek Medical Center, Walnut Creek, CA Department of Head and Neck Pathology, Guy's and St Thomas' NHS Foundation Trust, London, UK.

A novel DEK-AFF2 fusion was recently reported in 4 nonkeratinizing squamous cell carcinomas of the sinonasal region and skull base, including 1 with exceptional response to immunotherapy, but it is not yet clear if this rearrangement defines a unique clinicopathologic category or represents a rare event. This study aims to characterize a larger cohort of carcinomas with DEK-AFF2 fusions to assess whether they truly constitute a distinctive entity. Among 27 sinonasal and skull base nonkeratinizing squamous cell carcinoma that were negative for human papillomavirus and Epstein-Barr virus, RNA sequencing identified DEK-AFF2 fusions in 13 cases (48%).

COVID-19 lung injury as a primer for immune checkpoint inhibitors (ICIs)-related pneumonia in a patient affected by squamous head and neck carcinoma treated with PD-L1 blockade: a case report.

J Immunother Cancer 2021 02;9(2)

Department of Medical Oncology and Hematology, Humanitas Clinical and Research Center - IRCSS, Humanitas Cancer Center, Milan, Italy

By the beginning of the global pandemic, SARS-CoV-2 infection has dramatically impacted on oncology daily practice. In the current oncological landscape, where immunotherapy has revolutionized the treatment of several malignancies, distinguishing between COVID-19 and immune-mediated pneumonitis can be hard because of shared clinical, radiological and pathological features. Indeed, their common mechanism of aberrant inflammation could lead to a mutual and amplifying interaction. Read More

Mediators Inflamm 2020 30;2020:6716908. Epub 2020 Dec 30.

Department of Otorhinolaryngology, Union Hospital, Tongji Medical College, Huazhong University of Science and Technology, Wuhan, Hubei, China.

Background: Head and neck squamous cell carcinoma (HNSCC) is a common malignancy that emanates from the lips, mouth, paranasal sinuses, oropharynx, larynx, nasopharynx, and from other pharyngeal cancers. The availability of high-throughput expression data has made it possible to use global gene expression data to analyze the relationship between metabolic-related gene expression and clinical outcomes in HNSCC patients.

Method: In this study, we used RNA sequencing (RNA-seq) data from the cancer genome atlas (TCGA), with validation in the GEO dataset to profile the metabolic microenvironment and define potential biomarkers for metabolic therapy. Read More

Image-guided interstitial brachytherapy boost for keratinizing squamous cell carcinoma of inferior wall of the nasopharynx.

BJR Case Rep 2020 Dec 21;6(4):20200005. Epub 2020 Aug 21.

Department of Radiation Oncology, National Cancer Center Hospital, 5-1-1 Tsukiji, Chuo-ku, Tokyo, Japan.

High-dose-rate interstitial brachytherapy (HDR-ISBT) is relatively rarely applied for the head and neck cancer because of its anatomical complexity and difficulty of applicator placement. However, its dose distribution is more confined even better than intensity-modulated radiation therapy (IMRT) and can deliver a higher dose while sparing surrounding normal tissues. In this case report, the effectiveness of HDR-ISBT as a boost following IMRT for keratinizing squamous cell carcinoma of nasopharynx was presented. Read More

SSTR2a is constantly expressed in lymphoepithelioma-like carcinoma with squamous differentiation other than that with glandular differentiation.

J Clin Pathol 2020 Nov 1. Epub 2020 Nov 1.

Department of Pathology, Peking University Shenzhen Hospital, Shenzhen, Guangdong, China.

Aims: Somatostatin receptor 2a (SSTR2a) is an important diagnostic marker of meningioma and neuroendocrine tumours and is frequently expressed in primary and metastatic non-keratinising nasopharyngeal carcinoma (NK-NPC). Since NK-NPC cases are considered a kind of lymphoepithelioma-like carcinoma (LELCs) which originate from the nasopharynx, information on the expression profile of SSTR2a in LELC in other sites with squamous and glandular differentiations is still lacking. This study aimed to assess the expression of SSTR2a in LELC of various organs and clarify its expression profile. Read More

Routes of Spread to Eye from the Notorious Neighbour i.e. Nose, Sinuses and Nasopharynx.

Indian J Otolaryngol Head Neck Surg 2020 Dec 6;72(4):411-415. Epub 2020 Feb 6.

Osmania Medical College/Government ENT Hospital, Koti, Hyderabad, India.

Due to close anatomical relationship of eye with nose and sinuses it is liable to get involved secondary to sinonasal and nasopharyngeal pathology. Sinonasal and nasopharyngeal pathology may present with varied ophthalmic manifestations. Ocular involvement from sinonasal diseases occur due to direct spread to orbit, venous spread due to valveless nature of veins, cranial nerve involvement, nasolacrimal apparatus involvement and intracranial spread.
